INSOLE WEEE. NSEBTION OF WIRE NET'I'ING.

Application filed September 5, 1935, Serial No. 54,'2, and in Germany December 29, 1924.

This invention relates to a sole to be inserted into boots or sh es, aid sole having an insertion ot wire netting. The commonly used soles ot this type have the inconvenience that the Wire netting has a plane surface so that the object to provide tor a layer ol' air of suliicient thickness beween the sole ot the boot and the sole ot' the toot is notI attained. The wire netting is sometimes ot 1o such rigidity that it does not adapt itselt to the movements ot the toot so that the blood circulation is impeded andthe toot gets numb and catches cold.

It has already been proposed to obtain a sutliciently thick air layer by giving to the .insole a corrugated shape but, as such soles are generally made from rigid or not resistantnlaterial the above mentioned ineonvenienees are not avoided orthe insole does not preserve its shape tor a sullicicnt length ot time.

The Wire insertion in the insole according to the invention consists ot corrugated Wire netting. .fin insole according to the invention in which a core of corrugated wire netting is loosely held Within an envelope acts like an air cushion owingl to its yieldability in every direction as the inngrisonedl air escapes according to the pressure exerted by the toot trom the heel to the ball and inversely. The variations ol' the shape ot tl e insole which result hereironi etiiect a massaging of the sole of the 'loot and activate the blood circulation. This elliect is increased by the tact that the toes of the l'oot at the Walking are able to execute gripping niovements Wheretrom results that the imprisoned air is still more agitated.

An embodiment of the invention is shown, by Way ot example, in the accompanying drawing in which Fig. l shows the insole in plan view, the outer cover being partly removed so that the inner arrangement is visible.

Fig. l*1 shows a longitudinal through the inner envelope.

Fig. 1b shows a Cross through the same.

Fig. 2 shows partial longitudinal section on greatly enlarged scale. f

Figs. 3 and 4.- illustrate the air circulation in the insole during the Walking.

section sectional View lhe essential constituent of the insole is a sheet o1 corrugated Wire netting l adapted to yield under the pressure of the loot in the longitudinal direction and in the trans verse direction. rlhis layer 1 ot corrugated ivire enclosed in a bag 2 ot horse hair` tissue or ol anvas rlhis bag 2 is enclosed between tivo layers 3 oil' a porous or absorbent material and the Whole is enclosed in an outer envelope 4. Owing to the closed shape the insole lorins a kind of air cushion which yields under the pressure exerted by the toot in Walking as shown in Figs. 3 and The variations of the shape ot the insole exert a massaging action upon the toot sole and assist in preserving the blood parrculation and the natural heat oll the toot. ilioniture and sive-at are absorbed by the laf-,reis l et porous or absorbent material, the

wire insertion l being Well protected against rusting by the layers 3 and by the cover ot horse hair tissue. Owing to the closed shape ot' the insole the cold or moist air which at the walking should penetrate through the sole et' the boot is prevented `from getting at the toot. 'lhe layers 3 of' absorbent material being bad heat conductors retain the natural heat in the toot. l

The elasticity ot the ivire netting offers the facility to produce mechanically in dentations at certain points to ailord accommodation for callonses or corns so that they ivill 0radnally disappear.`

l.' in insole comprising an outer envelope, an inner envelope, layers ot absorbent material between them, and a core oitl corrugated wire netting loosely disposed Within the inner envelope, the said outer and inner envelopesand layers providingl in combination an air tight covering around the said cere.
